VALVE.

SPECIFICATION forming part of Letters Patent No. 598,248, dated February 1, 1898.

Application filed April 23, 1896.

To all whom it mag concern:

Be it known that I, JOSEPH E. HEINDL, a citizen of the United States, residing at Richmond, in the county of IIenrico and State of Virginia, have invented a certain new and useful Improvement in Valves, of which the following is a full, clear, and exact description.

The invention relates more especially to a valve for use on fire-hose; and the object of the invention is to provide a valve which may be conveniently opened and closed and wherein leakage is prevented when the valve is closed.

The invention comprises a valve-casing and a rotary plug arranged therein, with eccentrics interposed between the valve-casing and the plug, whereby the plug is moved bodily at right angles to its axis of rotation, so as to be seated in a perfectly fluid-tight manner when the valve is closed and so as to be eased off fromthe seat in the act of opening, all as I will proceed now more particularly to set forth and finally claim.

In the accompanying drawings, illustrating my invention, in the several figures of. which like parts are similarly designated, Figure 1 is a vertical longitudinal section. Fig. 2 is a horizontal section. Fig. 3 is a perspective view of the cap. Fig. 4 is a perspective view of the plug. Fig. 5 is a perspective view of the end of the casing opposite the cap. Fig. 6 is a transverse section illustrating a modification. Fig. 7 is a horizontal section taken in the plane of line 7 7. Fig. Sis a plan View of the inner side of the capof the valveof Fig. 6, and Fig. 9 is aplan view of the form of valve shown in Fig. 6 with the cap removed and looking in at the cap end.

The valve-casin g a may be of any approved construction and supplied with an internallythreaded inlet end I) and an externally-threaded outlet end 0. Midway between these ends the casing is provided with a cylindrical valveseat cl, and the bottom of this valveseat is provided with an eccentric projection 6. (See Fig. 5.) The valve-plug fis a cylinder perforated transversely to form the port f to register with the inlet and outlet openings to make a straightway passage through the valve. This plug is provided on its bottom sat no. 528,714.. a. model.)

with a concentric segmental projection g, which cooperates with the eccentric e of the casing, and the head of the plug is provided with a parallel concentric segmental projection 9', which cooperates with an eccentric projection 7t on the cap 2'. The cap '1; is provided also with a lug-or stop-pinj, which cooperates with the projection g to limit the rotation of the plug.

The plug is provided with a stem 76, which projects through an opening in the cap '5, and the said cap may receive the stuffing box or gland Z, so as to surround the stem and make a fluid-tight joint therewith. The cap is shown as adapted to be connected to the casing by means of a flanged screw-ring m.

I prefer to provide a lining n of bearing metal adjacent to the inlet end of the valve,

in order to provide for the more secure seating of the plug when the valve is closed.

The plug may be rotated by means of a bail 0, which has a forked end to engage a squared projection on the stem is and which is swiveled to the other end by a screw p, although other means may be employed for rotating the valve.

The plug is fitted to the seat in the casing with an amount of clearance substantially equal to the eccentricity of the eccentrics e and h, and hence when the plug is rotated to open the valve the action of the eccentrics tends to move the plug at right. angles to the axis of rotation, and thereby the plug is eased off from its seat, and so also in the rotation of the plug to close the valve the eccentrics act to move the plug in the opposite directionat right angles to the axis of rotation and thrust it hard and tight to its seat.

In the modification shown in Figs. 6 to 9 in stead of the eccentrics shown I use a disk, washer, or roller 4", which is secured to an cecentric-pin 'r on the casing and cooperates with the concentric flange or projection r -on the plug, and the cap at the opposite end of the plug is made with an eccentric 3, having the surrounding annulus or annular roller sf, which cooperates with the concentric projection or flange s of the plug. By the provisionof the disk 0 and the annulus 8, both being removable members, repairs to the valve may be readily effected and the valve may be kept in a perfectly tight condition at all times.

I havethus shown two forms of my invention of valves wherein the plug is seated and unseated, by an eccentric movement; but I wish to be understood as not limiting my invention to these two special formsor to the mere details of construction.

What I claim is- 1. A valve provided with a rotary plug, a casing in which it is seated, and cooperating concentric and eccentric projections inter posed between the plug and its casing and adapted to shift the plug at right angles to its axis of rotation as the said plug is rotated Witnesses:
